[Libusb-win32-devel] Error in usb_submit_async

[<li...@st...>]

Hello,

I had a strange behaviour with usblib (libusb-win32-filter-bin-20060518). On my
development system evrything was fine, on another system (without MSDEV ...) a
call to usb_bulk_write(...) >>mostly<< failed.

I logged a error with usb_strerror() and got:
usblib ec:-22
usb_submit_async: submitting request failed, win error: Falscher Parameter

I first thought of dll-Hell due to MSDEV, but a update to
libusb-win32-filter-bin-20060827 fixed the problem :-)

Just for my curiosity ... what was the reason? "Falscher Parameter" sounds to me
like a interface problem.

Thanks a lot
Alexander
